Hannah PH Meters

[kingfisher]

My Hannah PH meter is malfunctioning. The 4.0 buffer will not setup correctly.
Internet search indicates that this is common on 99104 model.

I have changed batteries to no effect.Electrode renewal (circa 14 pounds) reputedly often fails too.

Has anyone found a solution please ? or can recommend economical replacement.

Hi
Sorry no luck with one myself,so I binned mine and stuck to the API test kit,for the majority of Koi Keepers the cheap test kits are more than adequate IMHO.

Regards Geoff

The Hannah does seem to be generally unreliable although mine did last four years.

There appears to be a plethora of meters on Amazon but no reviews from Koi keepers.

I have got test kits but the meter is better for my circumstances.
